Military Roads of the Mississippi Basin

In Short

This historical study traces five crucial military expeditions through the Old Northwest between 1778 and 1794. Archer Butler Hulbert examines George Rogers Clark’s marches to Kaskaskia and Vincennes, Josiah Harmar’s Miami Valley campaign, Arthur St. Clair’s disastrous defeat, and Anthony Wayne’s victory at Fallen Timbers. Blending archival research with physical field exploration, Hulbert charts the precise geographical traces, wilderness paths, and corduroy roads used by these armies. The book endures as a foundational work of regional geography, showing how military movement permanently opened the Ohio and Mississippi basins to settlement.

The Story

The narrative begins in the revolutionary era with George Rogers Clark’s daring campaigns in Illinois. In 1778 and 1779, Clark leads his men through the flooded, wild terrain of the Wabash region to surprise British garrisons at Kaskaskia and Vincennes. Hulbert focuses on the practical mechanics of this trek, analyzing how Clark’s men waded through waist-deep waters, felled trees across swollen creeks like the Petit Fork, and maintained morale through wild game feasts. By marching along ancient Indian traces and natural watersheds, Clark secures the Illinois country for the young American nation, forcing the surrender of the British commander Henry Hamilton.

Following the Northwest Ordinance of 1787, responsibility for frontier defense shifts from local militias to the federal government, sparking an escalating conflict with the Miami Confederation and allied native tribes. In 1790, General Josiah Harmar marches north from Fort Washington along the Little Miami River into the heart of the Indian country. Though Harmar succeeds in burning villages, crops, and winter food stores along the Maumee, his forces suffer severe casualties in ambushes set by native warriors. Hulbert argues that while Harmar’s campaign is widely branded a failure, it stuns the confederacy and proves that American armies can strike deep into wilderness fastnesses.

The conflict reaches a crisis in 1791 when General Arthur St. Clair leads a poorly prepared army northward through Darke County. Plagued by inadequate supplies, bad roads, low morale, and rampant desertion, St. Clair’s force constructs Fort Jefferson under extreme hardship. At dawn on November 4, 1791, native forces launch a devastating surprise attack on St. Clair’s camp. Surrounded in the forest, the American ranks break into chaos, resulting in one of the worst defeats in United States military history.

In the aftermath, the federal government attempts peace negotiations, sending envoys like General Rufus Putnam while native leaders insist on the Ohio River as an absolute boundary. When diplomacy fails, General "Mad Anthony" Wayne takes command. Wayne prepares meticulously, building secure supply forts along his advance—including Forts Hamilton, St. Clair, and Defiance—and training a disciplined force known as the Legion. In August 1794, Wayne advances down the Maumee River. At the Battle of Fallen Timbers, amid a forest strewn with trees knocked down by a tornado, Wayne’s well-organized troops decisively defeat the native forces, ending two decades of frontier warfare and securing the region for permanent American expansion.

How It Unfolds

Clark marches on Vincennes Clark leads his troops across the flooded prairies and swollen rivers of Illinois, keeping his men in good spirits with evening feasts while navigating uncharted watershed traces toward the British garrison.

Harmar strikes the Miami towns Advancing up the Little Miami Valley along established war paths, Harmar burns central Indian villages and crop reserves, suffering heavy personnel losses in tactical ambushes before withdrawing back south.

St. Clair’s march collapses St. Clair struggles north through mud and rain with an ill-equipped, starving army, building Fort Jefferson under severe supply shortages that trigger widespread desertion among his men.

The dawn slaughter at the Wabash Native forces completely encircle St. Clair's camp in a surprise morning assault, taking advantage of heavy gun smoke and concealed positions in the brush to crush the American line.

Wayne builds his supply line Wayne methodically constructs a network of heavily fortified outposts along his northern route, establishing a disciplined logistics chain to prevent the supply failures of previous campaigns.

Victory at Fallen Timbers Wayne pushes his army down the Maumee River into a zone of heavy storm debris, engaging the native confederacy in a decisive battle that secures American control over the Northwest Territory.

The People

• George Rogers Clark seeks to secure the western frontier from British influence; he relies on keen wilderness diplomacy and sheer bravado to lead his troops through flooded lowlands, ultimately capturing Vincennes and establishing American claims to Illinois.
• Josiah Harmar aims to crush native resistance along the Maumee and Miami rivers; despite burning native settlements, his troops fall into devastating ambushes, leaving him with a mixed reputation as a commander who achieved destruction at great cost.
• Arthur St. Clair attempts to execute Washington's orders to establish a permanent fort in the Northwest; hobbled by poor health, inadequate supplies, and mass desertions, he suffers a complete tactical defeat that destroys his army.
• Anthony Wayne seeks a decisive military victory to settle the frontier war; through rigid discipline, careful fort construction, and thorough supply planning, he leads the Legion to victory at Fallen Timbers.
• Little Turtle fights to defend his native lands and maintain the Ohio River as a permanent boundary; he organizes an effective tactical resistance that routs St. Clair before ultimately being overcome by Wayne's disciplined forces.

In Its Own Voice

"The spectacle, here presented, of officers inveigling soldiers forward, is one of the most singular in the history of the West."

Context: Hulbert describes George Rogers Clark and his officers wading through knee-deep mud alongside their men to keep morale intact.

"Every kind of snake seemed to nestle together in those brush heaps."

Context: Pioneer A. H. Dunlevy recalls the abandoned brush piles left behind at one of Harmar's camp sites in 1798.

"My Heart & mind is fixed on that River & may that water Continue to run & remain the boundary of everlasting Peice..."

Context: An Allegheny chief points to the Ohio River while speaking to General Wayne at Legionville, demanding it remain the border between red and white lands.

What It's Really About

Hulbert’s central argument is that military success in the early Republic depended entirely on logistical geography. The book demonstrates that the ability to identify natural watersheds, follow native trails, and construct durable roads through swamps was just as crucial to empire-building as tactical strategy. Beyond the physical paths, the work explores the clash between United States expansionism and native sovereignty, illustrating how control over key river valleys—the Miami, Wabash, and Maumee—determined the political destiny of North America. Hulbert shows how early military traces laid the literal ground for future railways and modern highways.

Why Read It Today

This volume appeals to readers of military history, historical geography, and regional Midwest history. Rather than presenting grand battlefield narratives from a high-altitude perspective, Hulbert delivers a grounded, boots-on-the-ground study of wilderness logistics. Reading the book feels like embarking on a detailed field survey alongside a early-twentieth-century historian who physically retraces corduroy roads, inspects overgrown bluffs, and cross-references archival manuscripts with modern railway lines.

The prose is precise and direct, though readers should expect the vintage style of an early-1900s academic work, complete with exact township descriptions, surveying notes, and period terminology regarding Native American tribes. The text does not shy away from the severe hardships of wilderness warfare—detailing the brutal cold, deep mud, fog-choked swamps, and severe supply shortages faced by eighteenth-century soldiers. What stays with the reader is a visceral sense of how difficult the physical landscape was, and how deeply modern infrastructure rests upon forgotten military tracks.
